From publisher blurb:
The Zombie Crypt is a D&D 5e adventure for 2nd to 4th level characters. It consists of 2-4 sessions in which the players explore a crypt that has been infested by a horde of zombies. The players are enlisted to rid the crypt of this undead incursion.
In the marshlands of Cutters Fringe, the silent mist forms a shroud that wraps around small, isolated communities and cloaks the practice of the dark arts. But Sidrata Lidner’s efforts to fend off death have failed and now his funeral procession is making its way towards Heatherfield Cemetery and the mausoleum where his ancestors rest. However, the locals will not allow his body to be buried amongst their dead. During the altercation that follows, the funeral carriage is overturned and the coffin tumbles over the bridge and into the river, smashing open on the rocks below. The toxic green blood from Sidrata’s body washes downstream, transforming the Willow Cutters into zombies as they work in the Osier beds. The green torrent continues to flow and froth, breaking upon the graveyard wall and penetrating the CoTorinth family Crypt. As it seeps through, the dead begin to rise from their peaceful slumber. If the crypt is not freed of this undead infestation, then the curse will spread throughout Uoltan and beyond to the marshland villages as Sidrata rises in a new undead form to reap terror on the land.
